Two main problems with the game as I see it:
1. It's poorly balanced. Half the classes are F tier levels of terrible. Damage mitigation is laughably bad for the most part, and given the amount of unavoidable damage you will take in a run (see point 2), the only way to play the game is to build with the aim of one-shotting every unit in sight every turn. This is easily done, as there are many ways to become so hilariously overpowered that a flick of your pinky will devastate mountains, though you ignore a considerable portion of the game's potential builds in doing so.
The game continually asks you to take things like bleed, burn, poison, or similar damage over time effects. None of them are exceptional as a source of damage, and most of them only trigger after enemy attacks, making them worse than useless. The point of aggression in action games is to kill the enemy fast enough that they don't have the opportunity to deal damage to you. Orienting a build around bleed, as the game wants you to, means that no amount of successful aggression on your part will remove your opponent's ability to damage you, and because the majority of the game's damage mitigation is a joke, you will get absolutely destroyed. It's strange that Shiny Shoe doesn't understand this, but it makes an amount of sense if you frame each fight within the context of Monster Train, where enemies attack first. This game, in many ways, plays the same as Monster Train, only with a Hades-ish reskin.
2. Enemy attack patterns lack variation, and as a result enemies frequently perform unavoidable attacks. If direct targeted attacks didn't exist or were very rare, if they were replaced with a rich variety of avoidable attacks, then combat would be far more compelling.
There are 2 basic types of untargeted, avoidable attacks made by enemies: they attack in a circle or semi-circle, or they attack in a line or a rectangular wave. If the player ends their turn within an unsafe area, they take damage, so combat on those turns becomes about managing movement to be able to land attacks while making sure to be able to move to a safe area before ending turn, also while avoiding triggering certain enemy abilities. This is interesting and fun, although a little simple given the lack of variation in enemy attack patterns. Dodging circles and rectangles is basic geometry, where it could be trigonometry, for lack of a better analogy.
Imagine: enemies attack in a wave, if they collide with another unit their attack continues in another direction; enemies attack in a forked pattern, with safe zones in between unsafe zones; enemies charge up attacks, and the type/direction/strength of attack can be manipulated by the player during the charge-up turns. There are so many easily imagined ways to create new and interesting ways for enemies to attack.
Instead of this kind of inventiveness, most enemies cycle between an indirect attack and a direct attack, or they only have a direct attack. A direct attack is one where the enemy will deal the same damage to you no matter where you are or what you do on your turn. The only way to avoid the damage is to kill the enemy before it can attack. This is uninteresting and unfun, and it turns what could easily be a game with very compelling fights into a game where you just click the button to make enemy die. Because these direct attacks exist alongside damage mitigation being generally unreliable and bad, the only consistently viable way to play the game to win is to make a build that instantly kills everything in sight every turn.
Big numbers make thing go boom can be fun, and I enjoy the game enough. You have a few solid lines to choose from that can carry any run. If the two points mentioned above had been developed differently, the game could've been very good. It's decent as is, and what can I say I'm a Monster Train enjoyer. Sometimes it's okay to dabble in some trashy reality TV.
